Any standard video source can be used including satellite receivers demodulators VCRs laser/DVD players and TV/security cameras.
The CT-SAMM employs highly stable synthesized frequency control. Setup and tuning is easy and straightforward taking advantage of the unit's front panel access to all level controls and indicators. Channel frequency information with FCC offsets is programmed into each unit at the factory.
Nonvolatile memory maintains channel selection in event of power loss. The CT-SAMM meets or exceeds government regulatory requirements including FCC group delay pre-distortion for color transmission and FCC Docket 21006 aeronautical offset requirements. Designed for commercial grade headend systems the CT-SAMM provides cable operators the engineering ease and flexibility associated with headend deployments existing headend upgrades and system maintenance.
These fully agile modulators allow the rapid creation of channel lineups faster channel reassignments and quicker replacement of failed modulators over traditional fixed frequency devices. Just as important the CT-SAMM's full agility directly improves the operator's bottom line by not requiring an inventory of fixed frequency spares necessary for on-going headend maintenance. Features.
